这段批处理 如何在复制的时候找不到文件时不让它弹出提示框 找不到文件

Answer 1

@echo off&setlocal enabledelayedexpansion
set yyyy=%date:~0,4%
set mm=%date:~5,2%
set dd=%date:~8,2%

set yyyymmdd=!yyyy!-!mm!-!dd!


net use \IPurpback "urpurp" /user:"back"
copy  "\IPurpbackurp数据库备份NG0002_backup_!yyyymmdd!.rar" "F:urp备份" 2>nul

"G:软件安装WinRARWinRAR.exe" e   "F:urp备份NG0002_backup_!yyyymmdd!.rar" "F:urp备份"
ren F:urp备份NG0002_backup.bak  2>nul

if exist  F:urp备份NG0002_backup_!yyyymmdd!.rar (
 del F:urp备份NG0002_backup_!yyyymmdd!.rar  2>nul
)

两种情况，一种用 2>nul  让他别显示出来，另外一种就用 if exist 作一下判断
